Function circles_of_radius_tangent_to_two 

pub fn circles_of_radius_tangent_to_two(
    radius: f64,
    targets: &[Target2; 2],
    tol: Tolerances,
) -> OgeomResult<Vec<TangentCircle>>

Circles of a fixed radius tangent to two targets: the same machinery with the radius row supplied.

Errors

OgeomError::Construction if the radius is not finite and positive, or the targets coincide.
